Mounting the base station to a tower
To mount the base station on a tower:
1 Mount a back board or plate to the tower.
This back board or plate is custom hardware supplied by you, the service provider.
Examples of material you may want to use for your back board or plate include a 1/4 inch
aluminum plate, 3/4 inch green-treated plywood, or 2/12 inch green treated lumber.
2 After you have mounted your back board or plate to the tower, mount the base station to
the plate using installation kit 123-0100-0130.
Mounting the base station to a 19 inch rack
Base stations can be mounted to a 19 inch relay rack. Typically, NextNet Wireless stages this
rack for customers as a service.
After staging, the base stations are mounted in the rack and wired to the TVS modules, the
power supply, the backbone switch, and grounding plate.
If you desire to stage your own relay rack, you must use two 19 inch brackets (part number
350-0100-0101) and at least one grounding plate (part number 30-0100-0020).
Connecting the antenna to the base station
This section provides tips you can use to connect the antenna to the base station. It also
provides step-by-step instructions for connecting the components to each other.
Antenna connection tips
Use the following tips when connecting the base station to the antenna:
• You connect the antenna to the base station using a coaxial cable. The size of the cable
depends on the distance between the base station and the antenna.
• The greater the distance, the larger your coaxial cable needs to be, in order to maintain
low signal loss.
• It is recommended that you keep signal loss to a minimum. At a maximum, the signal
loss should be no more than 2 to 3 dB, including all coaxial cable and connectors.
• Use short coaxial jumpers from the base station to the main coaxial line, and from the
main coaxial line to the antenna. It is recommended you use 1/2 inch flexible line, of the
shortest length possible, while still allowing the flexibility to make a good connection.
• The base station contains an antenna connector with a 1/4 inch wave stub lightning
protector. You do not need to place an external lightning protector in the coaxial cable.
Connecting the antenna to the base station
To attach the antenna to the base station:
1 Mount the antenna according to the manufacturer’s instructions.
2 Connect one end of a short coaxial jumper to the antenna. Connect the other jumper end
to the main coaxial cable.
3 On the base station’s antenna connector, connect one end of a short coaxial jumper.
Connect the other jumper end to the main coaxial cable coming from the antenna.
